INVOICE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 506,808, dated October17, 1893.

' Application filed May 25, 189,3. Serial No. 475,433. (No model.)

To all whom t may concern.-

Be it known that I, SAMUEL BING, a citizen of the United States,residingat Humansville, in the county of Polk and State of Missouri,have invented certain new and useful Improvements in Invoice-Holders, ofwhich the following isa specification.

The object of my invention is to provide improved means for quicklybinding together invoices, letters, dac., in such manner that they aresecurely held together in shape for ling.

The particular object of my invention is to operate the bindingmechanism at a greater speed than heretofore and with greater facility.

In the accompanying drawings,-Figure l is a perspective view of a bookor binder embodying my improvements. Fig. 2 isa cross section of thesame. Fig. 3 is a detail view of the binding mechanism, and Fig. 4 is aFig. 5 is a detail view of the devices for locking the sheets after theholders are filled. Fig. 6 is detail view of part of the bindingmechanism,

My improvements are designed to be applied to an ordinary book cover A.

The frame B, of the binding mechanism may be of sheet metal having ailat vertical portion b, a top ange b projecting backwardly, a flange b2at the bottom extending forwardly and connecting by a bend with a bottompiece or flange b3, which extends backwardly beyond the plane of thevertical portion b. The frame has also backwardly extending end piecesh4. The backwardly extending end pieces and top and bottom flanges aresecured to a suitably-shaped block C, secured to the back of the cover.

A series of needles D, tive being shown, are secured to a connecting barE, resting on the flange b2. Screws F, having ring handles f, extendingthrough openings in the flange b2, and into screw-threaded openings inthe bar E. The construction is such that by removing the screws, the barE, and the needles carried thereby, may-be separated from the frame.

A supplemental cover G, is secured to the needlecarrying bar in suchmanner that when the needles are filled with papers and removed from thecover A, the binder may readily be employed to cover the package. As

shown, the back g, of the binder is flexible and bears against theframe.

it extends over and around the bar E, being' which extends from one endof the frame to the other, and which is preferably L-shaped, thehorizontal portion resting on the inner edge of the papers, while thevertical portion The presser bar is perforated, as shown, and theneedles extend through these perforations loosely, so that the presserbar is free to work up and down when operated. v

Studs I, secured to the presser bar extend through slots J, in thevertical portion b, of the frame B, and serve to guide the bar andprevent endwise movement thereof, as the bar is raised up and down,toward and from the base of the needles. The ends of the studs I aresecured to a connecting barK, on the inner side of the frame and also ateach end to springs L, which normally tend to force the presser bardownwardly toward the base of the needles.

Between the ends of the connecting bar with which engages a cam-shapedlever M,-

pivoted to the frame at m, and pivotally connected at m' with a handlelever M', provided with a knob m2. The lever M, also carries a stud m3,against which the inner end of the leverV M is adapted at times to bear.A spring catch N, secured to the flange h of the frame, is adapted toengage with a tooth n, on the lever M, which raisesit to the properposition.

It will be readilyunderstood from the foregoing description that thebinding mechanism may be readily placed in position iu a suitable cover,and that the supplemental binder G, may be readily attached to the frameof the binding mechanism by simply taking out and replacing the screwsF.

In Fig. 2, I have shown anumber of papers secured in positiom When it isdesired to add more papers, the handle M is moved forwardly, asindicated in Fig. 4, and the lever M," is caused to engage with theconnecting bar K,Which, being connected with the presser bar H, causesit to rise until it has reached IOO the top of the frame, as indicatedin dotted lines in Fig. 4. When in this position, the catch N, willengage with the tooth n, of the lever M, and hold it in position againstthe force of the springs L. Papers may now be placed over the needlesand then by reversing the handle, the catch will disengage from thetooth n, and the presser bar will move back and firmly clamp the papersin position.

The frame is cnt away at cc, to accommodate the handle, so that it maytit closely Without interfering with the opening and closing of the bookcover.

It will be seen by inspecting Fig. 2, that the handle while inconvenient position for usewhen desired, it does not take up unnecessaryroom and does not interfere with the opening and closing of the bookcover.

So far as I am aware, I am the first to provide lever mechanism forraising the presser bar of a binder of this class. By such mechanism, Iam enabled to operate the binding mechanism with one hand, while theother hand holds the papers. After the needles are lled with papers, aguard bar O may be ernployed to nish the binding. This guard bar isprovided with vertical perforations corresponding with the needles andwith a longitudinal pipe or channel 0, adapted to receive awre P. Theguard bar is placed over the needles with the pipe or channel in linewith the eyes thereof, and the wire P is passed through the pipe andthrough the eyes of the needles, and the binding is thus completed. Thescrews F, may now be removed, thus separating the needle-carrying bar Efrom the frame, and this needle-carrying bar and the needles carriedthereby which are filled with papers may be removed and tiled away, anda new needle-carrying bar may be secured in its place in the cover andthe binder operated as before.

I claim as my invention- 1. The combination of a frame, a series ofneedles secured thereto, a perforated presser bar through which theneedles extend, a lever connected with the presser bar for raising andlowering it, a catch for holding the presser bar in an elevatedposition, and a handle for operating the lever.

2. The combination of a frame, a series of needles carried thereby, apresser bar having perforations through which the needles eX- tend, aconnecting bar on the opposite side of the frame, devices for connectingthis bar with the presser bar, springs for holding the bars in theirlowermost position, a lever connected with the bars, and a handle foroperating the lever.

3. The combination of a frame, a series of needles secured thereto, apresser bar through Which the needles extend, an operating lever,connections between this operating lever and the presser bar, springsfor holding the presser bar in its lowermost position,a handle pivotallyconnected with the operating lever, and a catch for holding the leverand handle in their elevated position.

4:. The combination of a frame having upper and lower iianges, a blockto which the frame is secured, a needle-carrying bar secured to aforwardly projecting angeof the frame, a presser bar having perforationsthrough which the needles extend, studs secured to the presserbar andextending through slots in the frame, a connecting bar to which thestuds are secured, springs for holding the connecting bar and presserbar in their lowerrnost position, a cam-shaped lever secured to theframe and engaging with a stud on the connecting bar, a handle pivotallyconnected with the lever for operating it, and a catch engaging a toothon the lever for holding it in its uppermost position.

In testimony whereof I have hereunto subscribed my name.
